Real Madrid had enough budget to bring in the players they wanted, but they didn't. Ancelotti and the Real Madrid management are very confident in the existing squad and they have answered all doubts with their good performance so far. This is not the first time Real Madrid has had many injuries to several main players, last season was the same, but they won two prestigious titles in both La Liga and the Champions League.
Bringing in players to act as cover for other injured players has most likely been in Real Madrid's transfer plans so far. They will definitely get it, but don't expect all the problems to be resolved, of course because it's not just the players who can make the team perform as well as expected.
) and even the hype was real until the season started , their problem currently is not the squad but the game play(you might not see it that way but this is what I think). If they want back up they can get no one is against it but if they don't change how they're currently playing they might still be having issue.They still have enough time to figure out alot of things before the season comes to an end(more than enough time) but at the same time I don't think Barcelona will also relax it their future games.
